Hello, I only heard of it now, despite a thorough training in the matter, that you can do something like that. I had the timing belt change made about 3 years ago by a friend. He meant at that time you don’t need a special tool and changed it. That was also possible, but as I have now determined he did not consider the tax periods. I have always been told my Ommi (2.5 V6 BJ. 94) has too little performance, now I also know why. Now to my actual concern. Does jmd in the Recklinghausen district know a workshop that rents out the special tool for adjusting the tax times? Greetings Meisterjäger Edit Is it even possible to adjust the tax times now (about 35 tkm) or can it only be done directly after installation?
